Upgrades GODMODE from a flag to a trait. (#86596)

## About The Pull Request
GODMODE has a lot of sources that toggle it. From admin-stuff to status
effects, components, actions and mobs which are supposed to be
invincible. It's better off as a trait than a flag, so we can manage
these sources.

## Why It's Good For The Game
See above.

## Changelog

🆑
admin: godmode is now a datum trait instead of a bitflag. This means the
process for toggling it is a little different now.
